Tell the truth
Always thought my lawnmower was running at top rpm like it suppose to. It was cutting fine. Installed this tach and saw its rpm was 450 rpm lower than recommended. Adjusted throttle cable to get up to the factory rpm and it runs and cuts a lot better. Air cooled engines need max rpm to operate efficiently and cool correctly.

Does the job
Five stars for easy to install.Four stars for accuracy as I have nothing to compare it to; its a tachometer for a lawn tractor. It appears to be accurate. I needed it as a benchmark to check engine rpms. It does seem to register appropriately.Four stars for instructions; the instructions on operation could have been a little clearer.Overall, this was a good purchase as it does what I needed it to do.

Stopped Working
It was easy to install and I ran the wire along the side of the frame and kept it in place with cable ties. After using the lawn tractor 3 times with the tach on it stopped working.

Works great
Was able to finally adjust the air mixture screw on an old bike of mine. While the battery doesn't seem replaceable, I knew that ahead of time and, for the price its sold at, it isn't a big deal.

No instructions on how to wire it up.
Not only were there no instructions on how to wire it up, but there was exposed black and red wires coming out the end, so any touching to the engine or frame would have rendered it useless. Also it is very slow to read RPMs and takes about 5-10 seconds to settle near the RPM range that the motorcycle is actually at. But overall it works, just need to use it with the expectations that it is slow and accurate within 10-100 RPMs.
